` WHEEL on PULLEY. l

To all whom t may', concern:

Be it known that'I, GEORGE T. GUY, a citizen of the UnitedStates, residing at Oneida, in the county of Madison and State ofNew York, have invented a certain new and usefulVVheel or Pulley, of which the following is a specification. f n" f l f' This invention has for its .object a wheel or pulley which is particularly simple, tight and rigid in construction but possessing sufiicient flexibility to be clamped to shafts varying in size, larly economicalin manufacture and readily attachable to the shaft; andthe invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. Y

ln describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. Y Figure 1` 's an elevation of-a pulley ernbodying my invention. Y.

Fig. 2is a sectional view thereof Von line 2 2, Fig. 1.. Y

iFig. 3 is an inner face viewof one of the sections of the hub.

This pulley comprises generally, a hub having a circumferential hollow rib, the interior of whichopens into the bore of the hub and spokes attached opposite each other in pairs to the outer said rib by fastening means extending Vthrough the spokes and said Vflanges and placeable 1n position through the flanges, and the spokes from the inside ofk said rib. .Y

The hub is divided intotwo lsections or halves provided with means for 'clamping the sections together onto the shaft.

1 and 2 designate the sections of the hub,

andV 3 is the circumferentially extending arc-shaped hollon7 rib, the opposite walls 4, 5 of which are spacedu apart vand constitute flanges to which the spokes are secured. TheV interior of thel rib 3, that is, the 4space between the flanges 4,15 opens into the'borev 6 ofthehub so that the fastening means for. the spokes can be placed in position fromthe interior of the hub sections.

The hub sections also includeV sectional tubular portions 70u opposite sides of the rib 3 and two vpairs ofjaws 8, 9 at the ends of the sectionsl, 2 respectively, these jaws 8, 9 being clampedtogether in any suitable manner as by bolts 10 extending through the jaws 8, 9 and nuts threading o n the bolts,

12 are the spokes.` rlhe spokes as here shown areformed of sheet metal and have raised ribs 13 extending 'lengthwise thereof and flanges 14 on opposite sides of the rib, the inner ends of the spokes lapping the flanges 4, 5. respectively and being secured thereto by fastening members as rivets 15 l extending from the interior of the rib 3 or from the Vspace between thevflanges 4,*-5

through the flanges 14 of the spokes.

Usually, clamping or stiffening .pieces as 16 are provided at the inner ends of the spokes, these clamping ypieces being indi-` Y vidual to the spokes and having ribs and flanges corresponding with the ribs 13 and The` fastening members 15 also pass through the flanges of the clamping pieces 16. l

The spokes ysecured to the flanges 4, 5 are arranged with Vtheir vinner ends opposite to Said spokes are usually arranged opposite each other in pairs and the membersof the pairs converge asthey approach the rim 11 of the wheel, and are sev cured as by rivets 17 at their outer ends to the rim `and are also secured together near their outer ends as by rivets 18 extending through their flanges 14. The rivets 17 eX- tend through the outturned ends 19 of the spokes which ends 19 lap the inner face of the rim. V

Owing tothe hollow rib 3 vmaximum spoke or arm receiving area is provided as the spokes are opposite 13o-each other and hence twice the numberv of spokes can be provided on the same hub as heretofore, this feature being off-importance especially Furthermore, the pulley isreadily'assembled as any variations or un-uniformness in the rib 3 due to molding as well p as" iin-uniformness, ywithin certain limits, in the lengths of theV spokes is offset bythe fact that eachl spoke is attached individually to the flanger4 or 5 and the perforations in the flanges 4, 5 and thespokes for receiving the rivets canbe properlyA located for each individual spoke and each spoke, owing to the hollow rib 3, can be individually secured to the opposing center the' spokes.

Furthermore, owing to the rib 3, a maximum number of spokes can be used and each has sufficient bearing on the rib to be rigidly secured thereto, and owing to the arrangement of the spokes, the rim is readily arranged concentric Withrthe center of the pulley irrespective of any variation as all rims for a given size of pulley will be the same, andwhen attached to the spokes will y Although the pulley when assembled is particularly rigid nevertheless vit is flexible enough to provide a positivefcompression on the shaft on which it is mounted, upon tightening of the bolts 10.

What I claim is:V i
